FREDERICK J. HAZARD, OF BELLEVILLE, ONTARIO, ASSIGNOR OF THREE- FOURTHSTO STEPHEN EDWAY FULLER, OF COLBORNE, CANADA.

REAPING AND MOWING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 263,288, dated August22, 1882.

Application filed February 23, 1882. (No model.)

To all whom it may concern Be it known thatI, FREDERICK J AMES HAZ- ARD,a subject of Her Majesty the Queen of Great Britain, residing atBelleville, in the county of Hastings, Province of Ontario, and Dominionof Canada, have invented a certain new and useful Improvement in Reapingand Mowing Machines, of which the following is a specification.

My invention relates to a peculiar draw and push out motion given to theknives by the in troduction of certain straps which are attached by oneend to the knife-bar and bythe other to the finger-bar, and thus makingeach knifepoint,when in motion, describe a segment of a circle. Thismotion will make the work of cu tting easier, and tend to compel themachine to clear itself, and thereby prevent clogging.

Figure l is a'plan ot' the cutting apparatus of a machine embodying myinvention. Fig. 2 is a transverse section of the same.

Similar letters refer to similar parts in the views.

K is the finger-har, which is connected in the usual manner with theframe of any reaper or mower in general use, and is provided with ashoe, L, and toe M. p

O is the knife-bar, which is connected by the pitman J with the workingparts of any ordinary reaper or mower, which can have its mechanismreadily modified, so as to impart to the knife-bar double the throwwhich is generally used.

0n the finger-bar are the guards N, as in ordinary use. Three of theseguards are elongated backward a sufficient distance to receive the endof the straps P, by means of which the width of the finger-bar isreduced, which would otherwise have to be of an extreme width .toreceive the ends of the straps, and add unnecessarily to the weight ofthe machine. These straps connect the knife-bar with the finger-bar, andare constructed and secured as follows:

The pins Q are riveted to the knife-bar, and pins q to the elongatedguards at n, and are to receive the ends of the straps. These strap endsare hushed with rubber R, and havetube-bearings S, of metal, to receivethe pins Q and q, and are held in position by the washers T and nuts t.

This device will give to the knifebar a smooth and, comparativelyspeaking, noiseless motion, and will largely decrease the jerking andpounding motion which usually occurs in this class of machines. Theknifebar, being thus attached to the finger-bar, will when setin motion,partake of a transverse or lateral motion, as well as of a longitudinal,producing a rocking motion, and will cause the knife-points to describesegments of circles, as shown in dotted lines. It will thus be seen thatwhen the knife-bar is at the center of its stroke the straps will beperpendicular thereto, as shown in dotted lines P, and the knifepointscovered by the guards immediately on leaving that position in eitherdirection the knives draw in to the guards; but on making thereturn-stroke the knives push out until the center of the stroke isagain reached,when the operation is repeated, producing what I designateas the draw and push out, which, coupled with the long stroke, providesa cutting apparatus which will do bctter work with less power, and willnot be so liable to get clogged.

U U are keepers fixed on the finger-bar to act as guides for theknife-bar, but only come in contact with the fin ger-bar at the cars aa, the space intervening between them, next to the finger-bar, beingopen to prevent any dirt, hay, or other substance accumulating andclogging the machine.

122 is a lip onthe toe M to act as a guard for the outer knil'e when theknife-bar is eX- tended.

I am aware that prior to my invention reaping and mowing machines havebeen made with a long stroke, and they have also been made with thedraw-cut. I therefore do not 93 claim the former; nor doI use or claimthe latter, as I consider that there is a distinction between thedraw-cut and the draw and push out; but

\Vhat I do claim as my invention, and desire to secure by Letters Patentof the United States, is-

The combination of the strap P, pins Q and q, rubber R, tube-bearings S,and elongated guards n with the finger-bar K and knife-bar too 'O,producing the draw and push cut, as shown and specified.
